Definitions

  • the invention relates to a method for operating an optoelectronic Contrast button, in which a contrast mark is applied with transmitted light depending on the transmitted light reflected by the contrast mark a reception signal is generated and the reception signal is amplified becomes.
  • Contrast scanners are used to detect those with a contrast mark Objects.
  • the contrast mark reflects the transmitted light without Change in wavelength, or remit due to luminescence excitation in a wavelength range shifted with respect to the transmitted light. Part of that reflected or remitted by the contrast mark Transmitted light is received by the contrast button, amplified and the contrast of the contrast mark with its surroundings evaluated.
  • the operation of known contrast scanners is in disadvantageously on the detection of a predetermined selection of Contrast marks limited.
  • each-in step on the basis of the received signal checks whether the transmitted light reflected by the teach-in mark to the category of diffuse reflection or the category of geometric Reflection.
  • Luminescent marks fall into the first category and contrast marks that diffusely reflect the transmitted light or essentially absorb (black marks).
  • Against fall shiny contrast marks under the category of geometric reflection such as mirrors, reflectors or glossy film that the Reflect the emitted light mainly in the direction of the contrast button.
  • the method thus enables automatic categorization the contrast mark to be detected. Based on this simple A distinction is activated a gain factor for the determined category of reflection an optimal resolution of the contrasts supplies.
  • the invention thus offers an increased range of use for the contrast scanner, since this applies to brands of the diffusely reflective category as well also used for brands in the geometrically reflective category can be.
  • the design effort for realizing the invention is small since only the one carried out as part of the "teach-in" step Checking and selection in the already existing evaluation logic must be programmed, but no new components required are.
  • the inventive review of the reflection category has the advantage that not based on the type of contrast mark, but on Basis of the actually detected received signal over the one to be selected Gain factor is decided. This will, for example in the case of a contrast mark designed as a glossy film, which, however, is located at a comparatively large distance from the contrast scanner and therefore leads to a relatively low received signal, the higher gain selected according to the category of diffuse reflection.
  • the process automatically takes into account the respective Scanning distance or a level difference caused by different scanning distances of the received signal.
  • the basic setting of the gain factor is, for example, in the factory empirically and specifically for the preferred application of the contrast scanner determined and programmed into this.
  • the categories of reflection are preferably differentiated on the basis of the level of the received signal relative to a predetermined discrimination level. So it is checked whether the intensity of the reflected and received signal corresponding to received light exceeds or falls below the level of discrimination, or whether that Receive signal within one of two predetermined discrimination levels level window formed.
  • reception signals occur during operation of the contrast scanner are determined and evaluated for the same contrast mark different wavelength ranges of the reflected or received light, then preferably "teach-in" step and the selection of the gain factor for these different Wavelength ranges carried out separately. With others Words become an individual reinforcement for each of the colors considered selected.
  • the invention further relates to an optoelectronic contrast scanner, the is suitable for carrying out the method according to the invention.
  • This Contrast scanner has at least one transmitter for emitting the transmission light towards the contrast mark, a receiver for reception of the reflected or remitted transmission light and for generating of the corresponding received signal, an amplifier for amplification this received signal with an amplification factor, an evaluation unit to evaluate the received signal and a control unit which the implementation of the "teach-in" step and the selection of the Gain factor, and, if necessary, a repetition of this Steps to be controlled.
  • the transmitter 13 has a transmitter in a housing 11 13, which is formed, for example, by an LED or a laser diode is.
  • the transmitter 13 emits a transmission beam 15 of the visible, infrared or ultraviolet wavelength range, which after passing through a Transmission lens 17 outside the contrast button on a contrast mark or Learning mark 19 hits, which is attached to an object 21.
  • the transmission beam 15 is at least partially in by the contrast mark 19 Reflected in the direction of the contrast button, wherein it as the receiving beam 23rd after passing through a receiving lens 25, a photoelectric receiver 27 acted upon by an amplifier 29 and a control and evaluation unit 31 are connected downstream.
  • the control and evaluation unit 31 is also with the transmitter 13, a trigger button 33 and an optical Display element 35 connected.
  • FIG. 2 shows the signal levels S of different ones generated by the receiver 27 and not yet amplified reception signals.
  • Fig. 2 shows the signal levels R1, R2 of a shiny and thus highly reflective Contrast mark 19, the signal levels W and G of a diffusely reflective white or gray contrast mark 19 and the signal levels D1, D2 two dark, almost black contrast marks 19.
  • 3a, 3b and 3c show the signal levels V1, V2 and V3 of those shown in Fig. 2 Receive signals after their amplification with the amplification factor A1, A2 and A3.
  • the signal levels V1, V2 and V3 are percentages with respect to the output dynamic range of the amplifier 29.
  • the contrast scanner shown in FIG. 1 is operated as follows:
  • the basic setting is the gain A1, which is used for Detection of diffusely reflecting contrast marks 19 is provided.
  • a series of contrast marks to be subsequently detected 19 becomes a teach-in mark 19 in the beam path 15, 23 of the contrast button, and the release button 33 is actuated.
  • the "teach-in” step is triggered, in which the transmitter 13 from the Control and evaluation unit 31 causes the transmission beam 15 to be emitted and the receiver 27 as a function of the teach-in mark 19 reflected transmitted light generates a received signal and this to the Amplifier 29 passes on. There the received signal with the gain factor A1 amplified and to the control and evaluation unit 31 continued.
  • FIG. 3a shows the result of the amplification with the amplification factor A1:
  • Those amplified signal levels V1 that are diffusely reflecting Mark 19 correspond, that is, the signal levels W, G, D1 and D2 distinguishable from each other after their reinforcement.
  • the two signal levels corresponding to a highly reflective mark 19 R1, R2 indistinguishable in the saturation range of the gain A1 (100% in Fig. 3a).
  • Procedure categorically checks whether the relevant for the specific application the amplified signal level V1 corresponding to the teach-in mark 19 below or above a discrimination level U1 (Fig. 3a).
  • This level of distinction U1 is factory-set in the control and Evaluation unit 31 has been programmed.
  • the level of differentiation U1 can, for example, have a value between 70% and 90% of that in the 3a to 3c each shown output dynamic range of the amplifier Own 29.
  • the level of differentiation lies U1 just above the signal level W of a diffusely reflecting white contrast mark 19 with the gain A1 is reinforced.
  • the control and evaluation unit 31 selects one lower gain factor (signal levels R1 and R2 in Fig. 3a) and checks again whether the signal level V1 is now below the discrimination level U1 lies.
  • Gain factor A2 By successively reducing the gain factor in this way as well by correspondingly repeating the "teach-in” step such a gain factor A2 is finally reached, for which the signal level V1 corresponding to the teach-in mark 19 is the differentiation level U1 falls below.
  • the gain factor A2 thus achieved is maintained for the subsequent detection operation, and it will no further "teach-in” step carried out. That way, for example Gain factor A2 determined is shown in FIG. 2.
  • Fig. 3b The illustrated example of the learned signal level R2 and the achieved gain reduced with respect to gain A1 A2 is shown in Fig. 3b.
  • the two each have a shiny contrast mark 19 corresponding and previously in the saturation range (Fig. 3a) located signal levels R1, R2 can clearly differ from each other as well also distinguished from the signal level W of a white contrast mark 19 become.
  • the contrast scanner shown in FIG. 1 can thus be taken into account simple differentiation criteria and without any significant additional effort optionally for diffusely reflective and for glossy contrast marks 19 are used, each with full dynamics and accordingly high resolution.
  • the explained change in the gain factor becomes the amplifier 29 is displayed by the evaluation and control unit 31 and it becomes, for example when using an integrator for the amplifier 29 by change the integration time achieved.
  • the level of discrimination is preferably in a range between 10% and 30% of the output dynamics of the selected gain.
  • the learning method can be as follows to be expanded: If again based on a basic setting of the gain factor A1 in the first “teach-in” step in the explained check of the level of distinction U1 a shortfall the same is determined - without changing the gain factor A1 - additionally checks whether the teached-in reinforced Receive signal V1 also below a further level of differentiation U2 lies.
  • This further level of distinction U2 is preferably in a range between 10% and 30% of the output dynamics the gain set in each case.
  • the Gain factor while repeating the "teach-in" or checking step gradually increased until the amplified signal level of the considered Teach mark 19 exceeds the further distinction level U2.
  • the gain factor thus selected is used for the following Detection mode selected. For the example of the Signal level D1 this state is reached with a gain factor A3, which is much higher than the original gain factor A1.
  • FIG. 3c shows the result of an amplification with the amplification factor A3.
  • the signal level D1 is now just above the further discrimination level U2, and it can do significantly better from the neighboring one Signal levels D2 are differentiated than at the original gain A1 (Fig. 3a).
  • the output dynamic range of the amplifier 29 regardless of the choice of the gain factor A1, A2 or A3 and for example 0 to 5 volts or - after one Digitization - 256 bit. So the larger the selected gain factor A1, A2 or A3, the smaller the input dynamic range, in other words, the area that can still be distinguished after reinforcement Signal level S.
  • the selected gain factor A1, A2 or A3 is displayed on the display element 35.
  • the teach-in mark is dependent on the received signal 19 and the selected gain factor A1, A2 or A3 determines an operating switching threshold when it is exceeded or undershot in the subsequent detection mode of the contrast button Item detection signal is triggered.
